WILLIAM H, MENSCHING, OF BROOKLYN, NEW YORK.

' 'roon HOLDER-I To all whom it may concern.-

Be it known that I, WILLIAM H. MEN- SCHING, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in a ToolHolder, of which the following is a specification.

My invention relates to an improved'tool holder adapted to adjustably'retain an edged tool therein. The primary object is the provision of aportable tool holder to be used in connection with an abrasive surface,for rrinding or sharpening of the tool, and whic is adapted tobeused asa plane, or grooving tool.

Another object is the provision of a tool holder having novel means forready and accurate adjustment of the tool held thereby, to any desiredangle for sharpening or cutting.

With these and other objects in view, which will be apparent from thedescription, my invention resides in the novel combination,construction, and arrangement of parts hereinafter described andclaimed, and illustrated in the accompanying drawings, of which;

Fig. 1, is a plan View of the holder,

Fig. 2, a side elevation, showing a tool in position,

Fig. 3, a section on line 33 of Fig. 2,

Fig. 4, a detail of a part employed.

Throughout the description and the several views, like referencenumerals designate like parts. In the preferred form the holdercomprises a substantially rectangular frame formed of two similaropenwork castings l and 2, provided at their ends with ears 8 andfastened together by suitable securing means at positioned in the ears.The sides of the frame comprise upper bars 5 and lower bars 6, withdiagonal webs 7 extending therebetween. These webs are provided witharcuate slots 8, for a purpose to be hereinafter described.Correspondingly slotted side plates 9 are suitably secured over thesides of the frame for greater structural strength, as well asconvenience in handling the device.

Disposed between the sides of the frame and substantiallv intermediatethe ends, is the tool clamping and adjusting member, comprising a baseplate 10, pivoted at its lower end to the bottom bars 6 of the frameSpecification of Letters Patent. 7 Patented Jan 3,1922, Applicationfiled February 17, 1921. Serial No. 145,8811 i by means of pins 11journalled in the lower bars and disposed in lugs 12 formed on theplate. An integral, substantially U-shaped frame extends from the sidesof the plate 10 laterally thereof, to form side walls 13 and an outerbar 14, spaced from the plate and parallel therewith. The walls 13 arereduced toward bar 14, whereby the bar is aligned with the centralportion of the base plate 10.

Bar 14 is provided with a central thickened portion 15 internallythreaded to receivea winged bolt 16 carrying a clamping plate 17 onitsinner end, whereby a tool 18 may be clamped in the holder betweenbase plate 10 and the clamping plate 17. The angular adjustment of thetool is obtained by means of set screws 19 disposed through the slots 8and threaded into integral lugs 20 on the rear face of the base plate10. The heads of the set screws '19 are preferably winged, to bearagainst the side plates 9 for frictional engagement. Adjacent the webs7, and also the opposite end portion of the frame, steel rollers 21 arejournalled between the lower frame bars 6; the peripheries of therollers extending beneath the frame. For the purpose of insuringrigidity to a tool carried in the holder, I provide keys 22 havingchanneled heads 23 adapted to be engaged over the upper edge of the baseplate 10 between the side walls 13 and the tool. These keys are intendedfor use with small size bladed tools such as chisels and the like andmay vary in size to meet the individual requirements.

The device is adapted to be rolled over a plane abrasive surface, suchas emery and the like, and the rollers will serve to dis tribute oil inan efficient manner.

In operation, a desired tool is inserted in the holder andclamped'between base plate 10 and plate 17 with the edge of the toolprojecting below the frame the distance desired. The angle of the edgeis then adjusted by moving the clamping member on the pivots 11 andlocking it in position by means of the set screws 19.- It is obviousthat with the proper blades, the device may be used as a plane, orgrooving tool, the operation being the same.

While I have shown and described certain details which enter into theconstruction and operation of my invention, Iv desire it to beunderstood that I do not limit myself to these, but may use any such aswill fall within the scope of the invention as claimed.

I claim: a 1. A device of the character described comprising asubstantially rectangular frame having side and end walls, a platedisposed I in the frame between the side walls and pivoted thereto, aclamp support carried by,

said plate, a clamp in said support for clamping a tool against saidplate, means carried bysaid plate for slidable engagement with the sidewalls of said frame for angular adjustment of said plate relative to theframe, and supporting rollers in the 3. In a tool holder, a portableframe,

rollers arranged therein for supporting said frame, a plate pivoted inthe frame, a clamp carried by said plate, an edgedtool retained in saidclamp and extended beneath said frame, and means carried by said plateadapted to i slidably and kadjustably engage the sides of the frame forangular adjustment of the plate. 0 4. A tool holder comprising a framehaving side and end walls, supporting rollers arranged between the sideWalls, a clamping member adapted to receive an edged tool disposed inthe frame and comprising. a base plate pivoted at one end to the sidewalls of said frame, an integral U shaped member extending laterally ofthe base platebetween the side Walls .of the frame, a a

bolt threaded in said U shaped member, a clamping plate carried by saidbolt, the side Walls of said frame being slotted, lugs on said baseplate, and setscrews disposed in said lugs and positloned in said slotsfor v clamping engagement with the side walls of the frame for angularadjustment or" the clamping member in the frame. a

In testimony whereof I afiix my signature.
